  1. Transmission & Driveline
    The drive gear inside my Muncie for the speedometer just seems to spin on the shaft when I stick a finger inside where the driven gear is installed. I'm fairly sure it's supposed to be pressed onto the main shaft, correct? If so, would I need to remove the transmission to fix this? ...or can I...

Well...

    I have a 1968 M20 that was professionally rebuild for me. It has not been installed since. I also have the correct Hurst shifter and kit for the first gen Camaro. Both new still in the box. I really don't want to sell them out right but will consider offers. I am in need of either a t56 or a...

    Hey everybody, Got a '69 camaro with Muncie 4 Speed and factory Hurst shifter. Need to redo reverse lights because I do not have lock-out linkage installed (nor think I can install it with headers on car). I don't like the aftermarket hurst switch personally, with the exposed electrical...

    I've had this reverse lockout rod lying around the garage for a while, I'm trying to figure out what it goes to. It's 14 3/8" long and stamped 5767. Any info on it would be much appreciated Thanks

    When did the retention mechanism for shift levers on the Muncie transmissions change? At some point they changed from studs with nuts to a 'bolt'. Can anyone tell me the timing (ie. which year) for that change?

    Hi everyone, I wanted to come on here and give a huge recommendation for Jody of Jody’s Transmissions. After reading through the forums for months and months, I kept reading great things about Jody. Once I decided to move forward with my replacing my busted Muncie I reached out to him. We...

    I would like to install a Muncie 4-speed in place of the Powerglide in my ’68 Camaro. Is there a way to do this without having to cut the floorboard? I read somewhere about an offset shifter from Hurst that eliminates having to modify the floorboard, but from what I’ve seen online I think that...

    My shifter doesn't fit the hole in the trans tunnel. I recently changed to the 67 Hurst mount that attaches to the transmission mount and u-bolt around the very end of the tailhousing. I have a Hurst Competition Plus shifter. The shifter can rotate forward some on the mount. But with it...

    I replaced my speedo driven gear tonight with a 17 tooth purple part# 3987917 and I'm still 8 MPH slow on the speedo. So when the speedo reads 20 I'm going 28 or when the speedo reads 40 I'm going 48 MPH. So is there a smaller tooth count driven gear that I can go to? Or is there something else...

    I got my Muncie pulled apart today. I was expecting some carnage inside... and wasn't disappointed! My 1st gear had a few teeth completely stripped off and the countershaft had a number of teeth worn down as a result. It was ugly. I will of course need to order replacements for those two...

    Hey everyone, I'm rebuilding the Muncie 4 speed from my 67 and just finished Step 1: pulled it out of the car. That crossmember was not fun to get out... As I was looking inside the bellhousing, I noticed that the hole that the transmission slides into didn't really look straight. Is this...

    Hi guys, I was given a box with two shifter bodies, and a bunch of loose rods. Can't find numbers on some of the rods, and the rods that do have numbers I have not been able to find information online for them. One of the shifter bodies is a Hurst (says so, Hurst part#3915401), the other shifter...

    I have a m21 trans which had a Pontiac style Tail shaft. I replaced it with a Chevy one And everything seemed to go well when I swapped Them in my 67 camaro. Once everything went together, I could get The car to only go in reverse! There appears To be no neutral and none of the gears engage...
  16. What's it worth?
    I've got a Feb '69 Muncie M21 P9B14B in very good condition. I would rather have a M20, so I'm thinking of selling the M21. It's dirty, but inside it looks very good. No ears broke off and no holes stripped as far as I can tell. It just needs to be cleaned up and new seals around the shifter...

    Decided to tackled the rebuild of my M20 on my own and I finally got it completey disassembled. All internals seem to be in good shape, with the exception of the reverse and reverse idler gears. Before I order a rebuild kit for all the typical wear parts, I want to get opinions on the level of...

    Hey I have my transmission out of the car to replace the clutch and I wanted to update the front retainer nut and gasket since I had a slight leak and it was out anyways. I also ordered a new front bearing since it looked worn out. I had no problem getting the nut off but how do I remove the...
